The child’s proud grannie Dolores Aveiro revealed in an approved biography published in July 2014 in Portugal that she had picked the youngster up from a private hospital in Florida.

Ronaldo’s family has always refused to discuss whether his son was born to a surrogate mum, despite claims by a former nanny that the footballer’s sister Katia had told her he had two Mexican mums.
